Ozone (臭氧) levels increased, and ash from the fire fell on faroff sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling. t have a onesizefitsall solution and requires a bination of new technology, preventative measures and changing people39。 （3）考查細(xì)節(jié)理解。根據(jù)第二段中的“Responsible for collecting waste, the drone will begin operations in Dubai Marina in November after a year of trials with local partner Ecocoast.”可知，這種無(wú)人機(jī)是用來(lái)清理垃圾的，故選C。More measures should be taken to make water clean.C.The severity of ocean garbage pollution.D.It is a rubbish collector.D.t have a onesizefitsall solution and requires a bination of new technology, preventative measures and changing people39。s oceans. One paper from December 2014 estimated that over a quarter of a million tons of ocean plastic pollution was afloat. According to RanMarine, the WasteShark is available in both autonomous and remotecontrolled models. Measuring just over five feet by threeandahalf feet ( meters by meter), it can carry up to 352 pounds of rubbish ( kg) and has an operational battery life of 16 hours. By 2016 there were approximately 150 million tons of plastic in the world39。 WasteShark also has the abilities to gather air and water quality data, remove chemicals out of the water such as oil, and heavy metals, and scan the seabed to read its depth and outlines, said Oliver Cunningham, one of the cofounders of RanMarine. Fitted with a collisionavoidance system, the drone uses laser imaging detection and ranging technology to detect an object in its path and stop or back up if the object approaches.s around the perimeter (周邊) or through the city itself. The drones are that last line of defense between the city and the open ocean, added Cunningham. WasteSharks are operating in Dubai, South Africa and the Netherlands and cost $ 17, 000 for the remotecontrolled model and just under $ 23, 000 for the autonomous model. intention is to have the collected rubbish recycled or upcycled.

We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere. Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, watts per square meter of area burned are soaked up by the earth from greenhouse gases, but watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.（1）According to the new findings, taking steps to prevent northern forest fires may ________. A.protect the forests and the environment there（2）The following are all the immediate effects after a forest fire EXCEPT ________. A.ashes from the fire fall on the ice surface and take in more radiation from the sun（3）Earlier studies about northern forest fires ________. A.suggest that the fires will speed up climate warming（4）The underlined phrase soak up in the last paragraph most probably means ________. A.absorbedallow more snow to reflect more sunlight into space and thus cool the climateC.根據(jù)第二段中的“This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions”這樣的措施最終導(dǎo)致了北部地區(qū)的氣候變暖。故選C。根據(jù)最后一段中的““ watts per square meter of area burned are soaked up by the earth from greenhouse gases, but watts per square meter will b
